2004 Z71 with RPO NP8 4WD Es electronic transfer case.

Z71 2004 with RPO NP8 4WD Electronic Transfer Case After partially disassembling the transfer case it took two liters to fill up. This is the required liquid for these NPO cases. The fresh fluid seems to be helping the truck run smoother than before. It still had the original fluid in it as far as I can tell, but refilling the case with new fluid didn't seem to damage anything. I will always use this for my truck and its transfer case.

Pros
